The present invention has for its object a winding machine adapted tothe winding of loops made of elastic threads under tension, saidelongated skeins being for instance adapted for use 5 as an extensibledevice or a shock absorber, for

example in aeroplane landing gears.

Said winding machine is particularly remarkable in that the tension ofthe elastic thread during the winding is controlled by means of amovable tensioning member, preferably adjustable, which causesperiodically the unrolling of some length of thread.

In the accompanying drawing:

Fig. 1 is a perspective view of the winding machine.

Fig. 2 is a partial vertical section showing the automatic device forregulating the tension or" the elastic thread during the winding of theskein.

Fig. 1 is a diagrammatic view or" the machine for winding the skein.Said machine comprises a main frame or table 7 having bearings 8, 9 inwhich is rotatable a reel 10 carrying the elastic thread used for themanufacture of the skein.

Said reel 10 is provided with a locking device which may consist of astrip 11 attached at one end to the table 7 and connected at itsopposite end by a rod 12 to a lever 13 pivoting on an axle 14 mounted onthe frame 7. At the end of the lever 13 is mounted a counterweight 15whose action automatically applies the said strip 11 against the reel10, thus locking the latter. At

the other end of the main frame is a horizontal shaft 18, rotatable inbearings l61'7 and carrying at one end, at the side of the frame, ahandle 36 19, by which it may be turned. Upon its other end is keyed acarrier 20 in the form of a board. On said board may be secured aremovable support provided with two spindles on which the loop is to bewound.

According to the invention, a device is provided for adjusting thetension of the elastic thread during the winding.

Said device, which may have any desired arrangement, is preferablyconstructed as follows:

The thread (Fig. 1) proceeding from the reel 10 to the spindles l or 2carried the removable support secured to the board 26, passes over twosupporting pulleys 36, 37. Between said pulleys, a weight 38 (Fig. 2) issuspended from the thread 35 by a pulley 39. Said weight has in itslower part a recess 40 adapted to contain ballast for regulating theweight. At its upper part,

above the pulley 39, the said weigt 38 carries a small vessel 41containing mercury 42. The device consisting of the weight 38 and vessel41 is (Cl. Z42- 45) freely slidable in a vertical guiding tube 43carried by the table '7 or" the machine. Above the weight are disposedtwo metallic points or rods A l constituting two electric terminalsforming parts of a circuit supplying an electromagnet 45 disposed abovethe counterweight 15 of the lock- Lig member for the reel 10.

The operation is as follows:

The reel 10 of elastic thread is then mounted in its bearings 8, 9; thefree end of the thread is taken out and the thread 35 is placed upon thesupporting pulleys 36, 3'? and also upon the intermediate pulley 39carrying the counterweight 38. The end of the thread is then attachedaround one of the spindles 1 or 2; the locking member 11 is released,and the excess of thread used for the initial placing of the thread iswound back upon the reel 10. This winding bacl: of the thread on thereel 10 is stopped when the weight 38 is in its proper place in thelower part of the guide tube .3; the elastic thread 35 being thus givena suitable tension.

The handle 19 is then rotated whereby the thread is wound upon thespindles l or 2. The reel 10 is now stationary, as it is locked by thestrip 11 which is under the control of the counterweight 15. The weight38 will thus rise until the two points 44 enter the mercury 42 of thevessel 41. The circuit of the electroinagnet 45 is thus closed, theelectromagnet 45 raises the counterweight 15, thereby releasing the reel10. Said reel rotates to deliver elastic thread and the counterweight 38descends. At this time, the current ceases to act upon the counterweightl5, and the weigh descends again locking the reel 10. The operationabove described is then resumed in such manner that the tension of thethread 35 will be maintained at a practically constant value.

As the board 20 continues to rotate, the thread 35 is wound in acontinuous manner upon the indles l, 2 in order to form the skein. Whennumber of strands of said skein is sufficient, the winding is stopped.The thread is cut cit, and the last strand of the skein is attached inany suitable manner.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is:

In a machine for windin an elastic thread, rotatable supply reel forsaid elastic thread, eceiving means for said thread, means adapted movesaid receiving means in a continuous n anner, two guiding pulleysbetween said reel and said receiving means on which said thread is ingdevice adapted to normally hold said reel stationary and to beintermittently disengaged from said reel, and means actuated by saidroller when in its upper position and adapted to disengage said lockingdevice from said reel, this latter means being so timed as to disengagesaid locking device during the time during which said roller is movedfrom its upper to its lower posiion.
